IEC 61300-2-44:2013 specifies a test to determine the influence of flexing under tensile load of the strain relief of fibre optic devices. The intention is to simulate the number of flexing cycles which would typically be experienced during service life. This test is applied to both single fibre cable and multiple fibre cable. This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- revision of Figure 1;
- change of fibre length from the flex point to the weight.
Key Words: flexing under tensile load of the strain relief of fibre optic devices
